Why Use a Social Share Preview Validator?

When you share a link on social media, each platform reads your page's Open Graph meta tags and Twitter Card tags to generate a rich preview card. If these tags are missing, incorrect, or poorly optimized, your shared links can appear broken, show the wrong image, or display truncated text.

LinkPreview.io lets you validate your meta tags across all major platforms before you publish. See exactly how your content will appear on Twitter/X, Facebook, LinkedIn, Slack, Discord, and Google Search results — and get specific recommendations to fix issues.

Unlike scattered tools that only check one platform at a time, LinkPreview.io gives you a unified view of all platforms with both large and compact card variants, so you can catch problems before your audience does.

Frequently Asked Questions

What are Open Graph tags?

Open Graph (OG) tags are HTML meta tags that control how your content appears when shared on social platforms like Facebook, LinkedIn, and Slack. The most important tags are og:title, og:description, og:image, and og:type.

What are Twitter Cards?

Twitter Cards are meta tags (twitter:card, twitter:title, twitter:image) that control how links appear when shared on Twitter/X. The two most common card types are "summary" (small thumbnail) and "summary_large_image" (large image).

What's the ideal image size for social sharing?

The most universal size is 1200x630 pixels (1.91:1 aspect ratio), which works well across Facebook, LinkedIn, and Slack. For Twitter's large image card, 1200x675 pixels (2:1 ratio) is recommended. Google rich results use smaller thumbnails around 92x92 pixels.
